Specification of Letters Patent.

Application filed April 3, 1908. Serial No. 424,954.

Patented Jan. 5, 1909.

To all whom it may concern:

Be 113 known that 1, JOHN SOHROEDER, a

citizen of the United States, and a resident of Davenport, in the countyof Scott and State of Iowa, have invented a new and ImprovedMotor, ofwhich the following is a 'full clear, and exact description.

cember 10, 1907, wherein the actuating agent is'ordinarily Water, butmay if desired be other motive fluids such as steam, air, etc.

The invention has for its purpose the provisionof a motor embodying inits construction an oscillatory cylinder provided with a working piston,and having valve-controlling means for alternately admitting andexhausting the motive fluid to and from the cylinder at opposite sidesof the piston, the valve being referably actuated from the pistonthrough the usual driving shaft by a segmental gear in mesh with apinion fixed to the valve and provided with a radial arm through which avalve-rod is slidable, having stop collars.

The invention further contemplates the adoption ofcheck-valves at ornear opposite ends of the cylinder for the admission of air when wateris used as a motive agent, by which the exhaust of the water from thecylinder is easily effected, giving the motor a smooth regular motionand at the same time admitting of the closing of the valve earlier, andan economical use of the actuating fluid.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a side elevation of the preferred embodiment of my im rovedmotor as applied to a washing mac ine, the latter being shown partly insection; Fig. 2 is a plan of the construction shown in Fig. 1; Fig. 3 isa central vertical longitudinal section through the cylinder; Fig. 4 isa rear end elevationof the motor, showing the valve-rod in section; Fig.5 is a vertical section through the controllin valve; Fig. 6 is avertical section throug the valve, showing it in a different positionfrom that shown in Fig. 3 and Fig. 7 is a perspective view of the valve.

I have shown the motor applied to a washing machine, in which relationit is especially adapted to be used, although I recognize that it can beemployed satisfactorily for OWGI'IPUI'POSQS in general. The motor .em-

odies in its construction a base 10 preferably having edge flanges forstrengthening purposes, offset at its forward end, and provided at itsrear end with a vertical socket 11. In this socket is-adjustablysecuredby suitable means, as a set-screw 12, a post 13 having its upper endbifurcated for receiving the projecting portion of a valve-casing 14 towhich it is pivotally connected bya in or bolt '15. The valve-casing 14is rigi with and forms the rear head of a cylinder 16 which has theusual working piston 17, the rod of which passes through the forwardcylinder head 18 and the stuffing-box 19 secured thereto.

Leading into the valvecasing 14, referably at its top, is a supply pipe20 whic. connects through ports 21 and 22 res ectively with the rear endof the cylinder and theforward end of the same atthe front of thepiston, this last mentioned port, as best shown in Fig. 3, being formednot only in thevalvecasing 14 but also in the walls-of the cylinder andthe inner face of the front cylinder head 18. At the intersection of theports 21 and 22, a controlling-valve 23 is horizontally and revolublymounted in the valve-casing, and is in "the nature of a conical plug cutaway at its periphery for approximately a semi-circumference at thepoint of its length in a plane with the ports, as indicated at 24, and

is further out out at the opposite side to provide a slot 25 leadingthrough its smaller end and discharging into an elbow 26 threaded to thevalve-casing, and to an exhaust pipe 27. At the o posite side of thevalve-casing the stem of the valve 23 asses through a stuffing-box 28and throug a cup 29 envel- 0 ing said box, and is adjustab y secured tereto by a screw 30. This on has an arm 31 rigid therewith and providewith. an off set portion through which is threaded a setscrew 32, which,in connection with a like screw 33 threaded through the elbow 26, servesto adjust the valve 23 in the casing with such exactness that the leastossible friction will be developed when a flui -tight joint is secured.

The end or cover of the cup 29 is extended at its lower side, in whichis carried a pin 34, providing a bearing fora segmental gear 35, thelatter being in mesh with a pinion 36 fixed to the stem of the valve 23.The segmental gear 35 has a radial arm at its opposite side, throughwhich is slidable a valve- 41 is fixed to the driving shaft in mesh witha gear 42 fixed to a driven shaft 43, which in turn carries a fly-wheel44. Also fixed to the driving shaft is a crank 45 having the usual pinon which the piston rod 17* is jour 1 naled. This pin also serves tooperatively connect a rack 46 through a connecting rod 47, the rackhaving a pin 48 projecting from its rear face for this purpose. The rackis slidably supported in suitable ways carried by the base, the walls ofwhich are extended to provide bearings for a vertical shaft 49 extendinginto the tub, as shown in Fig. 1,

where it is constructed with the usual agitating arms. These arms arerevolved back and forth from the rack by a pinion 50 in mesh therewithand secured to the shaft 49. At or near each end of the cylinder is acheck-valve 51, which is set to open as a suction is created in thecylinder at the opposite sides of the piston when the latter isreciprocated.

In the operation of the motor, assuming the parts to be in the positionillustrated in Fig. 3, the water or other actuating fluid under pressurepasses from the supply pipe into the valve-casing, and is enforced bythe controlling-valve to pass through the port 22 to the front of thepiston. As the piston travels rearwardly a quantity of air is taken inthrough the forward checkvalve, and the fluid at the rear of the pistonis expelled through the port 21 and exhaust slot of the valve into theexhaust pipe 27. When the piston approaches the limit of its backstroke,

the forward collar on the valve-rod strikes the radial arm of thesegmental gear, and by it and the intermeshing pinion, revolves thevalve to the position shown in Fig. 6, thus cutting off the motive fluidfrom the port 22 and placing the same in communication with the exhaustslot of the valve and simultaneously connecting the supply pipe with theort 21. The piston as it travels forward likewise draws in a quantity ofair through the rear check-valve, which I have found to be an importantfactor in the smooth and regular running of the motor, and to alsoenable the cut-off of the water supply to take place earlier, that is,before the completion of the stroke of the piston, which obviouslyeconomizes the actuating fluid employed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. The combination of a base having a socket, a post adjustable in thesocket, acylinder having a working piston, a valve-casing pivotallysupported on the post, forming the head of the cylinder and rigidlyconnected therewith, a valve for controlling the admission and exhaustof the motive agent to and from the cylinder, and means operated by thepiston for actuating the valve.

2. The combination of a base, a post vertically adjustable on the base,a cylinder pivotally supported on the post and having a working piston,a valve controlling the admission and exhaust of the motive agent to andfrom the cylinder, and means for actuating the valve from the piston.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN SOHROEDER.
